To all whom it may concern: Be it known' that I, J OHN J. MORSE, a ctizen of the United States, residing at the city of St. Louis, State ofMissouri, have inventserial No. 715,707 which resulted in Patent No.1,095,019, dated April 28, 1914.

This invention relates to new and useful improvements in brake-shoes,and has for its object to provide a brake-shoe which is composed ofrelatively hard and soft metals in order to obtain increased frictionaland wearing qualities and at the same time to increase the strength andlongevity of the brake-shoe.

In the accompanying drawings forming part of this speclfication, inwhich like numbers of reference denote like arts wherever they occur,Figure 1 is a transverse sectional view of a brake-shoe embodying thepresent invention; Fig. 2 is a sectional view on the line 22, Fig. 1; Fi3 is a plan view of the pattern of the rein orcing element; Fig. 4 is atransverse sectional view of a brakeshoe having an alternate form ofreinforcing element located therein; Fig. 5 is a sectional view on theline 55, Fig. 4; and Fig.

6 is a plan view of the pattern of the reinforcing element, which isused in the structure depicted in Figs. 4 and 5.

The brake-shoe 1 is preferably formed of.

cast-iron and is reinforced by a plate 2 of wrought, ductile, or othertough metal, which plate is preferably located near the back of thebrake-shoe and is arcuated simi-- larly to the back of the latter. Theplate 2 bears a plurality of arms 3, some of which arms project from oneside of said plate and others project from the opposite side of saidplate, the arms 3 borne by one side of the plate 2 being spaced apartand arranged in staggered relation with respect to the arms 3, which areborne by the other side of said plate and are, also, spaced apart, asbest seen in the patterns of said plate depicted in Figs. 3 and 6. Thearms 3 are bent so as to extend diagonally through the body of thebrakeshoe from opposite sides of the plate 2, so

that the arms 3 borne by one side of said plate extend between the arms3 borne by the other side o-f'said plate, and, by this air rangem ent,not only anchor the plate 2 firmly 1n the cast-metal of thebrake-shoe,but increase the frictional qualities of the wearing part of thebrake-shoe. Said arms 3 may be ofsuch length that same will extendsubstantiallv straight from the sides of the plate 2 diagonally throughthe body of the rake-shoe to a point near the wearing face of thelatter, as depicted in Figs. 1 and 2,

or, if desired, said arms may be relatively long, in which case each arm3 is bent at the point 4 intermediate the end of said arm and its pointof juncture with the plate 2, so that'the part extending between thebend 4 and the ]11I1Ct111e Wlth the plate 2 diverges toward said'plate,and the part extending from the bend 4 to the end of said arm divergestoward the wearing face of the brakeshoe, as depicted in Fi s. 4 and 5.It should be understood that, i desired, the arms3 may be still longerand provided with more bends 4 than shown in Figs. 4 and 5.

The brake-shoe may be provided with the usual key lug 5 having the usualopening 6 therein or with a plurality of such key lugs, which lug orlugs may or may not be reinforced.

Itwill be evident that the wrought orductile reinforcing plate not onlyincreases the strength of the brake-shoe, but the presence of parts ofsame in the wearing part of the brake-shoe enhances its brakingqualities and thereby increases the longevity of the brakeshoe. Byreason of using a plate having .arms 3 as hereinabove described, thedisposionly may extendinto and form part 'of the wearing face of thebrake-shoe, but may take I the place of the inserts ordinarily .used. In

this way the plate at or adjacent to the back of the brake-shoe iscombined with the arts of same that may take the place 0 mserts in thewearing part of the brake-shoe, the result being the: provision of astronger and; more efiicient brake-shoe.

I claim:

1. A brake-shoe having a body portion including a wearing member whichextends toward'the wearing face of the shoe in an obli uely transversedirection, said wearing mem er bein of dilferent material from othermateria forming a part of the said body.

2. A brake-shoe having a body portion including a. plurality of wearinmembers which are angularly disposed wit respect to v each other andwhich extend toward the wearinig faeeof the shoe in obliquel transverseirections, said wearing mem ers being of different material from othermaterial forming a part of the said body.

3. A brake-shoe having a body portion composed of a plurality ofmaterials one of which is a tough metal and the other of which is agranular material, said body portionincluding members of the tough metalwhich are embedded in the anular material and which extend towar thewearin face of the shoe in transversely oblique d1- rections. v

e 4. In a brake-shoe, a plate of ductile metal located adjacent to theback thereof, said plate having extensions which are connected to thelongitudinal sides of the plate and project therfrom into the wearingpart of the brake-shoe, the free end portions of the extensionsterminating at points located adjacent to the longitudinal side of theplate opposite to the longitudinal side to which the extensions areconnected.

5. A reinforced brake-shoe com osed of east-metal and having a plate 0ductile metal located adjacent to the back thereof and arms borne bysaid plate and projecting Boat-ransversely from the longitudinal sidesof same into the wearing part of the brakeshoe, the arms borne by oneside of said plate being arranged in staggered relation with respect tothe arms borne by the other side of the said plate and terminating atopposite sides of the plate.

6. A reinforced brake-shoe com osed of thelongitudinal sides of saidplate into the wearing part of the brake-shoe and which are of a lengthsubstantially equal to the width of the plate.

7. A reinforced brake-shoe composed of cast-metal having a plate ofductile metal located adjacent to the back thereof, said plate bearing aplurality of arms which tproect transversely in spaced relation rom thesides of said plate into the wearing part of the brake-shoe, the armsborne by one side of said plate being arranged in staggered relationwith respect to the arms borne y the other side of said plate andextending between same in the wearing part of the brake-shoe.

8. In a reinforced brake-shoe, a plate hav ing transverse parts whichextend from the opposite longitudinal sides thereof toward each otherand toward'the wearing face of the shoe and which are of a lengthsubstantially equal to the width of the plate.

9. In a reinforced brake-shoe, a reinforcement therefor consisting ofintersecting parts transversely disposed with relation to the shoe andextendin from opposite sides of the shoe toward tie wearing face thereofand in opposite inclined directions alrlid terminating at opposite sidesof the s 0e.

10. In a brake-shoe, a reinforcement ing from opposite sides of the shoetoward the wearing face thereof, said parts crossing one another.

11. In a brake-shoe, a reinforcement therefor consisting of partstransversely disposed with relation to the shoe and extending fromopposite sides of the shoe toward the wearing face thereof, the outerends of said parts terminating at the sides of the shoe opposite to theshoe side adjacent to which latter the inner ends of the parts aredisposed.

12. In a brake-shoe, transverse intersecting reinforcements therein.

13. In a brake-shoe, reinforcements which extend toward the wearing faceof the shoe and intersect each other at points between the wearing faceand the back of the shoe.

14. In a brake shoe, a plate having a series of arms on each sidethereof, the arms on one side of the plate crossing the arms on theopposite side of the plate at points intermediate the ends of the arms.

15.In a brake shoe, sinuous reinforcements, portions of which intersectone another.

, 16. In a brake shoe, a plate and a sinuous extension connected to eachside of the plate and being disposed beneath the plate and extendingtoward the wearing face of the brake shoe.
